CAR-COUPLING.

SPECIFICATION forming part of Letters Iatent No. 248,452, dated October18, 1881.

Application filed June 11, 1881.

To all whom itmag concern Be it known that I, WILEY M. GRrsHAM, acitizen of the United States, residing in Oxville precinct, in thecounty of Scott and State of Illinois, have invented a new and usefulOar-Ooupler,of which the following is a specification.

My invention relates to that class of couplers in which the operation ofcoupling is antomatically performed and that of uncoupling effected fromeither of the sides of the cars.

The object of my invention is to construct a coupler which shall be safeto uncouple, simple in construction, and effective in operation.

My invention consists in various novel devices for accomplishing thesepurposes, all of which will be hereinafter fully explained.

In the drawings, Figures 1 and 2 represent perspective views of myimproved coupler in position for engagement; Fig. 3, a detail view ofthe coupling-pin and attachments; Fig. 4, a detail view of thecoupling-hook, and Fig. 5 a detail view of the weighted coupling-hookguide.

Similar letters of reference indicate corresponding parts throughout thedifferent views.

N is the bumper, in a slot of which the coupling-hookH is pivoted byashort bolt, I, passing through an eye formed in the rear end of saidhook. In the opposite side of the bumper a second slot, L, is formed,extending the whole depth of the same, and having flaring edges. 1n thelower forward part of said flaring edges an angle-plate, A, providedwith a weight, 0, upon its lower end, is pivoted by a short bolt passingthrough part of the bumper, and an eye, B, formed in the angle of saidplate. The longer arm of the plate, in its normal position, rests uponshoulders formed on the sides of the slot, and extending from the lowerpart of the same upward and backward to the coupling-pin. By thisconstruction the plate A acts as a guide for the hook H while the carsare being coupled, and, after being borne backward by the hook in theoperation of uncoupling, is returned to its normal position by theweight 0.

In the rear of the upper edge of guide A a transverse hole is formed inthe bumper,

(Model) through which the coupling-pin D passes. The outer extremity ofsaid pin is provided with a curve or arm, E, upon whose end is formed aring, through which passes a rod, F, provided with collars on eitherside of said'ring, and having weighted ends F.- There are also formed.upon rod F, in the same plane with the weighted ends F, stops G, whichwork in recesses m, formed in the sides and top of the bumper.Bythisconstruction,whentheweighted ends F are turned through an arc ofone hundred and eighty degrees, the rods may be laterally moved a partof their length and the pin D withdrawn from its position across theaforesaid slot,whereby the hook H is uncoupled. Upon dropping theweighted end the rod is turned, and one of the stops Gr prevents thereturn or jarring of said coupling-pin to its normal position. When thepin is in place the other stop G engages with the sides of the aforesaidrecess and prevents uncoupling.

In the middle of the face of the bumper is the recess J, provided withflaring sides, and through the forward part of the upper and lower sidesa perforation, K, is made,whereby, when it is desired, the ordinarycoupling link and pin may be used.

The operation of my improved coupler is as follows: When two cars fittedwith the same approach each other the hooks H first come in contact withthe guide-plates A at about halfway of the latters length. Following theincline of said plates they finally drop over the pins D, and the carsare coupled. When it is desired to uncouple said cars the weighted endsF are made to describe an arc of one hundred and eighty degrees, one ofthe rods F is pushed and the other pulled, and the pins D are therebywithdrawn and the cars uncoupled. lu the separation of the latter theguides A are drawn outwardly until the hooks pass over the ends, whenthe weighted arms F cause their return to normal position.

Having thus described my invention, what Iv claim isl. The combination,with the bumper N, of 5 5 pin D, of the pivoted angle-plates A 0,subvided with recesses M, and the pin D, of the angle-plate A 0, pinD,arm E, and rod F, prorod F, weighted ends F, and stops Gr, subvidedwith weighted arms F and stops Gr,subro stantially as and for thepurposes described. stantially as and for the purposes described.
